This invention relates to an improved type of incubator embodying amongother characteristics a heating apparatus adapted to keep the atmosphereat a constant temperature.

Another object of the invention contemplates'adelecting'ap aratus bymeans of which the heat may e evenly distributed within the bottom ofthe incubator.

An additional object of the invention comprehends fan members preferablylocated within the top of the' incubator to facilitat circulation of theatmosphere.

A cardinal object of the invention resides in the provision of racks andframes therefor to sustain eggs and by which the Asame may be tilted. YY A,

More specifically stated the racks are adapted for shiftingmovement totilt theV frames therefor. p

With the above and other'objects in view, the invention further consistsin the following novel features and details of construction, to behereinafter more fully described, illustrated in the accompanyingdrawings and pointed out in the appended claims. l

,In the drawings Figure 1 is a vertical sectional view taken through thecompleted invention.

Figure 2 is a sectional view taken on line 2-2'of Figure 1.

Figure 3 is a vertical sectional view-taken on line 34-3 of Figure 1.

Referring to the drawings in detail, wherein likelcharacters ofreference denote corresponding parts, the reference character 10indicates a pit' sunk within the ground and havin communication with afloor surface 11. y oil burner or other heating device, such asindicated at 12, arranged within vthe bottom of the pit is'adapted forconnection with a thermostat 13 through the instrumentality of a pipeline 14, the latter also being in communication with a fuel reservoir 15which may be arranged for convenient reiilling. An overiiow pipe 15 isin communicationwith the oil burner whereby excess-oil within the pitwill be carried oi instead of allowing the fumes therefrom to be`circulated within the incubator.

support receptacles 20 for water or other liquids which may beevaporated in conjunction with the heat, whereby the atmosphere will behumidied.

A deiiector 21, carried by and elevated from the iooring 11 immediatelyabove the pit 10, ,is adapted to collect and deflect or otherwise spreadthe heat from the pit across the flooring. A

Fans 22, carried within the roof 17 and havin communication with inletports 23, are a apted to keep the humidiiied atmosphere circulatingwithin the'l incubator due to the specific shape of the upper surface ofthe deflector upon the side and end portions thereof. Discharge port-s24 located adjacent the ends and within the roof of the incubatorhousing are adapted to provide the means toA facilitate emission of foulair.

The air currents from the fans directed upon the inclined surfaces orfacets of the deiiector will cause the heated or humidiiied air .to besucked or otherwise drawn outwardly from under the edges of the delectorand directed upwardly for contact with the eggs within the trays.

A vent pipe 25, extended from the heating element 12, is projectedthrough both the deflecting dome 21 and roof 17, whereby the gases maybe taken off from the heating element.

the humidity created in the evaporation of the l liquid within thereceptacle,pby said heat,

will producethe desired atmosphere for the purposes of incubation.

Standards 28, supported upon the flooring 11 at the ends of theincubator and having connection at the uppermost ends with theundersides ofthe roof 17, are arranged in spaced parallel relation uponthe opposite sides of an aisle within the housing. Access may be had toone end of the housing by one ofthe doors 18, inasmuch as the heatdeiector 2l extends above the floor and is arran ed' in the path ofmovement through sai aisle. For this purpose, other doors are providedwithin the sides of the housing to facilitate access to racks and traystherefor, he descriptions of which will presently fol- Racks 29,preferably of angle bar construction and in the nature of elongatedframes, substantially as illustrated in Figure 2 of the drawings, aretiltably mounted at inter- -me'diate points in their lengths upon rod ofthe drawings, the lowermost ends of the supporting bars 31 and 32 areelevated from the lioor surface 11 but when it is desired to tilt theracks 29 and trays 34 supported thereby, it is therefore necessary toremove bolt members 35 from locking arms.36 horizontall disposedadjacent the lowerinost ends o the standards 28 and the supporting bars31 and 32 will engage the upper surface lof the iiooring 11 asillustrated in dotted lines to the left in Figure 3 of the drawings.

The bolts 35 are also passed through the lowermost ends of the'supporting bars 31. .Removal of said bolts will permit tilting of theracks and trays to occupy either ofthe extreme positions,` asillustrated b the dotted lines in Fig-ure 3 of the drawings. Suchmovement is necessary at prescribed interf l vals to facilitate properincubation of eggs. Such action will valso causey the eggs to partiallyturn whereby other sides of the eggs may be heated.

The trays and stationary. Said stationary frames are utilized for thesupporting of chicks alread hatched. The chicks after breaking throngthe shells upon the tilting trays 34 are then transferred to the traysupon the stationary frames; the latter having reticulated bottoms,whebym'ore air will circulate around I the chicks to dry them olf.

vThe invention is susceptible of various Vwithin the housing, and

frames, located adjacent the ends of the turning or tilting trays 34,are A fall .within the scope of the appended claims.

- Having thus described the mvention, what is claimed is y1. In anincubator, a housing having a pit,

a heating element arranged within the pit,

moisteners for the air emitted from-said pit', a deiiector havinginclined surfaces and eX- tended over the pit and elevated from thebottom of the housing, `egg trays arranged an members directing aircurrents upon the inclined surfaces of the delector to cause circulationof the generated air around and aboutsaid trays.

2. In an incubator, a housing having a pit,
